Every year, many people in the United States consider having weight loss surgery. This kind of procedure poses a few health risks, both during and after surgery. A recent study has found that gastric bypass procedures and one of the newest weight loss surgeries, called a sleeve gastrectomy, essentially may trigger an acid reflux. The sleeve surgery removes over 3/4 of the stomach, and turns the remaining amount into a sleeve. Of those who received the sleeve surgery who already had GERD (severe acid reflux), only about 1/6 had resolved GERD symptoms after surgery. Since prolonged GERD can lead to swallowing problems or cancer over time, it is suggested that you discuss all of your weight loss options with your healthcare provider before you go under the knife to lose weight.
